Mortimer Ostow's most original contribution is to reject the conventional view that religion and psychological health are incompatible. He views these two impulses as not only interdependent but even indispensible for the shaping of a mature identity. Required reading for all who are concerned with the place of the spirit in the tumult of modernity.

Mortimer Ostow enriches our understanding of religious motivations as he weaves a powerful image of our spiritual nature. In his integrated vision, the light of science illuminates the perennial mystery of human faith and religious urges without diminishing the spiritual journey that is such an important feature of human life.

Mortimer Ostow, one of the most interesting psychoanalysts of our generation, has from the beginning of his distinguished career combined his interests in neurology, psychiatry, and psychoanalysis in the treatment of his patients and in his thinking about the mind. A scholar of the Talmud and a student of religion, Ostow addresses a family of interrelated issues—spirituality, religiosity, and mysticism—that have been ignored by both psychoanalysts and by students of the brain. An extraordinary book.
